My research mainly focuses on observational and theoretical astrophysics, with an emphasis on optical surveys, the transient universe, Type Ia supernovae progenitors, Cepheid distances, and the dynamics of few-body systems.

I am involved in many observational projects, but must notably, I am a founding member of the All-Sky Automated Survey for Supernovae (ASAS-SN or "assassin"). This is the first survey to scan the entire sky for transient objects in real-time and is currently the leading discoverer of Supernovae brighter than 17th magnitude.
